To all whom it may concern:

Be it known that l, W'ILLIAM a citizen of the United States, residing at Troy, in the county of Rensselacr and State of New York, have invented a new and useful Improvement in Boiler-Tube Gleaner-s, of which the following is a specification.

This invention relates to certain new and useful improvements in steam-boiler tube or line cleaners of that type which directs jets of steam into and through the tubes or flucs from the rear end of the boiler removing therefrom the soot and other extraneous matter and projecting the same out through the chimney or stack.

My present invention is also an im rovemcnt on the devices disclosed in lnited States Letters Patent $868,403 issued to me on October 15, 1907 and my application Serial No. 423,898, filed March 28, 1908. In the construction shown BRADLEY,

in Letters Patent #868,403, the operator could not positively determine what boiler tubes had been cleaned and in addition, the steam from the inner end of the discharge outlet frequently reached the boiler arch causing disii'itcgration thereof. Both of these dilliculties l have overcome in my present invention.

in my application for United States lictters Patent, Serial No. 42?),S9S, lilcd March .28, 1908 l disclosed a type of cleaner wiiich was perfectly operative and which obviated the dii'licultics set forth above in connection with the device covered by United States Letters Patent $868,403 but I have discovered a better construction with fewer parts for rotating the discharge end of the steam outlet and also imparting thereto in addition a radial motion by means of which each and every boiler tube is blown clear and clean of all soot or other extraneous matter.

I am aware of other patents than mine which have been allowed on boiler tube clean ers but ex crience has demonstrated their lack of abihty to perform the work for which they were intended especially in cases where the boiler tube area was extensive or the flues were of great length.

In my new construction 1 secure the entrance of the steam into the boiler fines in a more direct line and have reduced to a minimum the chance of difliculty arising from rust, corrosion or heat in connection with securing the radial motion of the steam outlet.

My new shifting mechanism consists of a fork and block operated by a shaft turned by a handle or controller which carries a spring pin engaging at set points with counter borlngs on the face or rim ofthe hand wheel. These set points are marked ,to indicate to the operator the articular rows of boiler tubes into which t e steam is being directed from the steam outlet. I have also deflected the upper section of the tunnel inclosing the steam outlet to prevent the steam from reaching t e boiler arch, and have secured greater ease of operation by lengthening the cylindrical sleeve and steam outlet thereby increasing the leverage of the shifting mechanism.
